Car Alarms: ford 250 super duty factory alarm, valet mode, dash area

Question
Is there any way to disable the auto arm feature on my factory alarm ? Every time I turn off the key , the alarm arms with a chirp after 30 sec . I cannot work on the vehicle or shovel salt out of the box without the alarm going off .
Thanks

Answer
It's an after market system
from your description.
And no, you need the manual for whatever alarm
you have there, but you can try to put it into
and out of Valet/overide mode.

To disarm it, locate and use the
valet/overide switch.

To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no
alarm at all. Repeat steps to put into user
mode.

Let me know how it goes.
